Resources and Settings
Table 2 lists the ModusToolbox resources used in this example, and how they are used in the design. For pin usage and
configuration, open the Pins tab of the design.modus file.
Table 2. ModusToolbox Resources
Resource Alias Purpose
Timer Counter PWM (TCPWM) PWM Generates 25 Hz, 50% duty cycle square wave
Smart I/O SmartIO Implements divide-by-4 sequential circuit
Digital Output Pin Pin_LED Provides visual feedback using the LED
Figure 2 highlights the non-default settings for the TCPWM.
